Abstract:TMs paper presents the mathematical mod el for the optimization of heterogeneous components I an d the method using sensitivity analysis and steepest descent method to optimize material propertiesthe component is then identifiedAfter searching for the materials from heterogeneous material database according to the corresponding optimum material data and combining the heterogene- OUS compo nentsthe material is synthetizedTo designerthis method is feasible and effective for the material design of heterogene-
OUS compo nents
Key words:heterogeneous componentsmathema~cal modelsensitivity analysis and optimizationsteepest descent method
